An AC voltage of the form ?v = 100 sin 1 000t, where ?v is in volts and t is in seconds, is applied to a series RLC circuit. Assume the resistance is 410 ?, the capacitance is 4.75 µF, and the inductance is 0.500 H. Find the average power delivered to the circuit.
A parallel plate capacitor has a charge of 2.66X 10^-11 C after being charged by a 15 V battery. The plates are seperated by 2.0 mm of air
A 78-kg base runner begins his slide into second base when he is moving at a speed of 4.2 m/s. The coefficient of friction between his clothes and Earth is 0.70. He slides so that his speed is zero just as he reaches base.
A 1348 kg weather rocket is launched straight up. The rocket motor provides a constant acceleration for 13.6 s, then the motor stops. The rocket altitude 29.6 s after launch is 2091 m. You can avoid any effects of air resistance. What was the rock..
A box slides down a 40° ramp with an acceleration of 1.260 m/s2. Find out the coefficient of kinetic friction between box and ramp.
A rigid tank contains 1.20 moles of an ideal gas. Determine the number of moles of gas that must be with Illustrate from the tank to lower the pressure of the gas from 24.2 atm to 5.30 atm. suppose the volume of the tank and the temperature of the..
A friend of yours is loudly singing a single note at 410 Hz when racing toward you at 26.1 m/s on a day when the speed of sound is 339 m/s. What frequency does your friend hear if you suddenly start singing at 410 Hz.
One possibility for a low-pollution automobile is for it to use energy stored in a heavy rotating flywheel. What is the angular velocity of the flywheel when it has a full "energy charge"
An alternating emf source with a variable frequency fd is connected in series with a 50.0 ? resistor and a 20.3 ?F capacitor. find the angular speed at which the phasors rotate
A 2.7 kg mass acceleration speed at 10 m/s2 in a direction 38? north of east. One of the two forces acting on the mass has a magnitude of 10.6 N and is directed north. Determine the magnitude of the second force.
The force of the wind on the sails of a sailboat is 300 N north. The water exerts a force of 210 N east. If the boat (including crew) has a mass of 310 kg, illustrate what are the magnitude and direction of its acceleration?
How fast is the mass moving at the top of its new path (directly above the peg)?
A 1200 kg car moving north at 27 m/s is struck by a 2165 kg car moving east at 11.0 m/s. The cars are stuck together. How fast and in what direction do they move at once after the collision.
